Hi All,

Its been a few months since I last posted about my search for a Z28. I ended up buying a car within a week of my search starting and I've loved driving/owning it.

I'm now thinking about replacing the exhaust manifolds/headers and sport cats. What are owners opinions on which brand to go for? Which diameter is recommended for an unmodified engine (I've just got the AHP heads)? Does anybody have a diagram/drawing of the Z28 exhaust layout? Do the factory manifolds have pre-cats in addition to the main cats?

Thanks in advance!
